I have a customer that wanted to put TeamViewer on 2 of his systems and once the TV is installed, both systems have the same ID.
TV: 14.3.4730
Windows 10 LTSB
Hello @RichardPercival,
Thank you for your message.
Your customer probably cloned the image of his device.
I think that the following article would be interesting for him: How do I use TeamViewer on cloned systems?
I hope this could help. If not, do not hesitate to ask your questions here.
Cheers
Jean
